Title: Gyratory equipment of construction machinery
Inventor: KUDO YOSHIO
IPC: B66C23/84
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To eliminate play of a gear without spoiling the engaging characteristic or the gear in gyratory equipment and prevent loads from swinging during the gyratory movement and increase the accuracy of the stop position. SOLUTION: A driving pinion gear 14 is fitted to the output shaft 27 of the first hydraulic motor and the reacting pinion gear 16.is fitted to the output shaft 34 of the second hydraulic motor. Both pinion gears 14, 16 are arranged in the peripheral direction of a ring gear 18 to mesh with each other. The feeding oil path 32 of the reverse rotation side of the second hydraulic motor 15 is branched from the feeding oil path 22 to the normal rotation side of the first hydraulic motor 13. The feeding oil path 31 of the normal rotation side of the second hydraulic motor 15 is branched from the feeding oil path 23 to the reverse rotation side of the first hydraulic motor 13. The second hydraulic motor 15 is rotated to the same direction with the driving pinion gear 14 due to the difference of the capacity of both hydraulic motors 13, 15 and hence, the reactive force is generated.  Accordingly, the state that both pinion gears 14, 16 push each other through the ring gear 18 is kept and hence backlash does not arise.

Abstract: PURPOSE: To prevent efficiency drop of a steam turbine etc. resulting from secondary flow by forming rotors in such a way as the fluid inlet angle at the end part of the rotors varies from the position at a specified height toward the end part.  
     CONSTITUTION: A dynamic vane 27 is twisted in such a way as the fluid inlet angle β gradually increases or gradually decreases followed by a gradual increase as the height increases from the root part 27a to the prescribed height H 1  27b, and increases in response to an increase of the rotation periphery speed caused by an increase of the raduis between 27b and 27c which is H 2  below the top part 27d, and further increase from 27c toward 27d. The values of H 1  and H 2  are decided based on the thickness of the region which is controlled by the secondary flow on wall section. The fluid inlet angles at the root section and the top section are so decided as they vary from the fluid inlet angles at H 1  and H 2  by I 1  and I 2 , or variances in the fluid inlet angles based on the difference in nozzle fluid outlet angle caused by the secondary flow.

Abstract: PURPOSE:To achieve discharging at a high-vacuum region to improve a working accuracy of a minute pattern using plasma etching by a method wherein a cylindrical anode and a cathode with a specimen holder close to the anode are installed in a reaction chamber, and a magnetic field is generated in the anode to perform etching. CONSTITUTION:A pair of parallel electrodes (cathodes) 2 and 3 and a cylindrical anode 4 are installed in a reaction chamber made of a quartz tube 1, and a magnet 5 is installed outside the chamber to generate a magnetic field. On the cathode 2, a specimen 7 to be etched is held. While generating an external magnetic field by applying a voltage between electrodes, a halogenide compound gas is introduced into the evacuated chamber, and discharging is made to etch the specimen 7. Cathodes 2 and 3 are grounded, and a D.C. voltage is applied to the anode. The cathode 2 supporting a specimen can be placed at a positive potential, and also an alternating current can be superposed between cathodes. Because a dissociation of plasma is increased with the presence of a magnetic field, discharge can be achieved at a vacuum of the order of 10<-2>torr or less,  and a working accuracy can be improved by the contribution of ions etching.
